Description

  The present invention relates to an information processing system, an information processing apparatus, an information processing method, and a program.

  Conventionally, print data is not printed immediately in response to a print instruction input by a user on a PC (Personal Computer) or the like, but is associated with the user name of the user and stored in a predetermined server or a storage device in the image forming apparatus. There is a system to save. When the user inputs a user name and password via the operation panel of the image forming apparatus, the image forming apparatus executes an authentication process for the user name and password. If the authentication is successful, the image forming apparatus causes the operation panel to display a list of print data associated with the user name among the print data stored in the storage device. The image forming apparatus acquires print data selected from the list information from the storage device and executes printing.

  According to such a system, since the printed matter is output when the user is near the image forming apparatus, it is possible to prevent the printed matter from being left unattended or accidentally taken by another person. Can do. As a result, the security of the printed information can be ensured.

  However, in the system as described above, only a user who has an account for receiving authentication in advance can execute printing. Therefore, for example, a visitor or the like who does not have an account has the inconvenience of having to request printing by a person who has an account. Therefore, it may be possible to prepare a common guest account for visitors. However, in this case, since a common account is assigned to a plurality of visitors, a certain visitor can operate print data of other visitors. As a result, the characteristics of the system such as ensuring the security of printed information may be lost.

  Furthermore, it is conceivable to install an image forming apparatus for a guest. However, it is difficult to say that this is an excellent solution because an economic burden increases and an installation space is required.

  The present invention has been made in view of the above points, and an object of the present invention is to make it possible to give an output authority even to a user who does not have an account necessary for outputting data.

  Therefore, in order to solve the above-described problem, an information processing system including one or more computers includes a receiving unit that receives an output request for data including a predetermined address via a network, and an address of the transmission source of the output request And a generation unit for generating user identification information indicating an output authority of data related to the output request when the user identification information is not specified by the specifying unit. A storage unit that stores output information of data related to the output request in association with the user identification information identified by the identification unit or the authority identification information generated by the generation unit, and the authority identification information. Included in the request according to the first transmission unit that transmits to the transmission source of the output request and the request transmitted from the device via the network The output information stored in the storage unit in association with the user identification information or the authority identification information, and a reply unit that returns the output information to the device, and each of the predetermined addresses included in the destination of the output request A determination unit that determines whether the address is included in the format notified to the address, and the first transmission unit includes the predetermined address in the format in the format by the determination unit. If it is determined that it is not, the authority identification information is not transmitted.

  Even a user who does not have an account necessary for data output can be granted output authority.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of a printing system according to an embodiment of the present invention. In the printing system 1 shown in FIG. 1, one or more user terminals 30, a mail server 40, a management server 10, an authentication server 50, a storage server 60, one or more image forming apparatuses 20, and the like are included in a LAN (Local Area Network). Alternatively, they are connected to be communicable via a network N1 such as the Internet. A part or all of the network N1 may be a wireless communication network. A mobile communication network may be interposed between the user terminal 30 and the network N1. Note that the printing system 1 is operated in a certain organization such as a company. In the embodiment of the present invention, the organization is referred to as “company A”.

  The user terminal 30 is an information processing apparatus that is directly operated by a user of the printing system 1. For example, the user operates the user terminal 30 to input a print request for the printing system 1. Examples of the user terminal 30 include a PC (Personal Computer), a mobile phone, a smartphone, a tablet terminal, and a PDA (Personal Digital Assistance). Each of the plurality of user terminals 30 may be a different model.

  In the present embodiment, users of the printing system 1 are classified into “regular users” and “guest users”. An authorized user refers to a user whose information is registered with respect to the printing system 1 (strictly, with respect to a user information storage unit 52 described later). That is, the regular user is a user who is scheduled as a user of the printing system 1. An example of a regular user is an employee of company A. A guest user refers to a user whose user information is not registered in the printing system 1. That is, the guest user is a user who does not have authority to use the printing system 1. As an example of the guest user, a person other than the employee of the company A can be cited.

  The mail server 40 is a computer that transfers e-mails transmitted from the user terminal 30 and e-mails transmitted from the management server 10. For example, the user terminal 30 transmits an e-mail including a print request to the management server 10 in response to an instruction from the user. Electronic data to be printed is attached to an electronic mail including a print request. The data format of electronic data is not limited to a predetermined format. Hereinafter, an electronic mail including a print request transmitted from the user terminal 30 is referred to as a “print request mail”.

  The authentication server 50 is a computer that manages a user name, a password, an e-mail address, and the like (hereinafter referred to as “user information”) for each authorized user, and executes processing using the user information. is there. For example, the authentication server 50 executes an authentication process in response to an authentication request in which a user name, a password, and the like are specified. Further, the authentication server 50 executes processing in response to a mail address existence confirmation request and a user name acquisition request corresponding to the mail address. That is, the user information includes the mail address of the user in association with the user name.

  The management server 10 is a computer that executes print data generation and the like for electronic data included in the print request mail in response to reception of the print request mail. The print data has a data format that can be interpreted by the image forming apparatus 20. The management server 10 transmits the generated print data to the storage server 60 in association with the user name of the user of the transmission request mail (sender) or the identifier generated for each print request mail. When the transmission source address of the print request mail is associated with the user name and managed by the authentication server 50, the user name is associated with the print data. When the source address of the print request mail is not associated with the user name and managed by the authentication server 50, an identifier generated for each print request mail is associated with the print data. Hereinafter, this identifier is referred to as a “PIN (Personal Identification Number) code”. The print data associated with the PIN code can be printed by inputting the PIN code to the image forming apparatus 20. Therefore, it can be said that the PIN code is information for identifying the output authority regarding the print data.

  The storage server 60 is a computer that stores print data transmitted from the management server 10.

  The image forming apparatus 20 is a device having a printing function, such as a multifunction peripheral or a printer. The image forming apparatus 20 is a device that executes printing of print data associated with the user name or PIN code input to the image forming apparatus 20 by the user from among the print data stored in the storage server 60. .

The management server 10 in FIG. 2 includes a drive device 100, an auxiliary storage device 102, a memory device 103, a CPU 104, an interface device 105, and the like that are mutually connected by a bus B.

  A program for realizing processing in the management server 10 is provided by a recording medium 101 such as a CD-ROM. When the recording medium 101 storing the program is set in the drive device 100, the program is installed from the recording medium 101 to the auxiliary storage device 102 via the drive device 100. However, the program need not be installed from the recording medium 101 and may be downloaded from another computer via a network. The auxiliary storage device 102 stores the installed program and also stores necessary files and data.

  The memory device 103 reads the program from the auxiliary storage device 102 and stores it when there is an instruction to start the program. The CPU 104 executes a function related to the management server 10 in accordance with a program stored in the memory device 103. The interface device 105 is used as an interface for connecting to a network.

  FIG. 3 is a diagram illustrating a hardware configuration example of the image forming apparatus according to the embodiment of the present invention. 3, the image forming apparatus 20 includes hardware such as a controller 21, a scanner 22, a printer 23, a modem 24, an operation panel 25, a network interface 26, and an SD card slot 27.

  The controller 21 includes a CPU 211, RAM 212, ROM 213, HDD 214, NVRAM 215, and the like. The ROM 213 stores various programs and data used by the programs. The RAM 212 is used as a storage area for loading a program, a work area for the loaded program, and the like. The CPU 211 realizes various functions by processing a program loaded in the RAM 212. The HDD 214 stores a program and various data used by the program. The NVRAM 215 stores various setting information and the like.

  The scanner 22 is hardware (image reading means) for reading image data from a document. The printer 23 is hardware (printing means) for printing print data on printing paper. The modem 24 is hardware for connecting to a telephone line, and is used to execute transmission / reception of image data by FAX communication. The operation panel 25 is hardware including input means such as buttons for accepting input from a user, display means such as a liquid crystal panel, and the like. The liquid crystal panel may have a touch panel function. In this case, the liquid crystal panel also functions as an input unit. The network interface 26 is hardware for connecting to a network such as a LAN (whether wired or wireless). The SD card slot 27 is used for reading a program stored in the SD card 80. That is, in the image forming apparatus 20, not only the program stored in the ROM 213 but also the program stored in the SD card 80 can be loaded into the RAM 212 and executed. The SD card 80 may be replaced by another recording medium (for example, a CD-ROM or a USB (Universal Serial Bus) memory). That is, the type of recording medium corresponding to the positioning of the SD card 80 is not limited to a predetermined one. In this case, the SD card slot 27 may be replaced by hardware corresponding to the type of recording medium.

  In the present embodiment, the image forming apparatus 20 does not necessarily have the scanner 22 and the modem 24. In other words, the image forming apparatus 20 may be a printer instead of a multifunction peripheral.

  FIG. 4 is a diagram illustrating a functional configuration example of the printing system according to the embodiment of the present invention. In FIG. 4, the management server 10 includes a mail receiving unit 11, an address designation determination unit 12, an unauthorized designation handling unit 13, an address confirmation unit 14, a PIN code generation unit 15, a print information generation unit 16, a response mail generation unit 17, a mail A reply unit 18 and a print information transmission unit 19 are included. Each of these units is realized by processing that one or more programs installed in the management server 10 cause the CPU 104 to execute.

  The mail receiving unit 11 receives a print request mail. The print request mail includes print target data that the user wants to print (for example, a mail text or an attached file). For example, the user transmits an email including data to be printed from the user terminal 30 to an email address of a specific domain (hereinafter referred to as “print request address”). The mail receiving unit 11 acquires a mail addressed to the print request address from the mail server 40, thereby recognizing that the mail is a print request mail.

  The address designation determination unit 12 determines whether or not the print request address is included in the correct format (is specified) in the print request mail. The state included in the correct format is a state in which the print request address is included in the print request mail in a format in which the print request address is notified to each address included in the destination of the print request mail. . In other words, the state of being included in an illegal format is a format in which the print request address is not notified to each address included in the destination of the print request mail (a format in which the print request address is concealed). A state where the request address is included in the print request mail. For example, when the print request address is included in the To field or Cc (Carbon copy) field of the print request mail, it is determined that the print request address is included in the print request mail in the correct format. On the other hand, when the print request address is included only in the Bcc (Blind Carbon Copy) field of the print request mail, it is determined that the print request address is included in the print request mail in an illegal format.

  When the print request address is included in the print request mail in an illegal format, the fraud specification handling unit 13 executes processing for suppressing printing based on the print request mail.

  The address confirmation unit 14 confirms whether or not the transmission source address is registered in the authentication server 50 by transmitting a request for confirming the existence of the transmission source address of the print request mail to the authentication server 50. When the transmission source address is registered in the authentication server 50, the address confirmation unit 14 acquires a user name corresponding to the transmission source address from the authentication server 50. The PIN code generation unit 15 generates a PIN code when the transmission source address is not registered in the authentication server 50. The print information generation unit 16 generates print information corresponding to the print request mail. The print information includes a user name, a PIN code, and the like in addition to print data and information related to a print job of the print data.

  The response mail generation unit 17 generates an electronic mail (hereinafter referred to as “response mail”) as a response to the print request mail. The response mail includes print job identification information based on each print data. The response mail also includes the PIN code when a PIN code is generated for the print request mail.

  The mail reply unit 18 returns a response mail to the transmission source address of the print request mail. The print information transmission unit 19 stores the print information in the storage server 60 by transmitting the print information to the storage server 60.

  The authentication server 50 includes a request response unit 51, a user information storage unit 52, and the like. The user information storage unit 52 stores user information for each authorized user. The request response unit 51 executes processing according to an authentication request, a mail address existence confirmation request, a user name acquisition request corresponding to the mail address, and the like. The request response unit 51 is realized by a process that a program installed in the authentication server 50 causes the CPU of the authentication server 50 to execute. The user information storage unit 52 can be realized using an auxiliary storage device of the authentication server 50 or a storage device connected to the authentication server 50 via a network.

  The storage server 60 includes a print information receiving unit 61, a print information storage unit 62, a print information providing unit 63, and the like. The print information receiving unit 61 receives the print information transmitted from the management server 10 and stores (saves) it in the print information storage unit 62. In response to the print information acquisition request from the image forming apparatus 20, the print information providing unit 63 includes the user name specified in the acquisition request among the print information stored (saved) in the print information storage unit 62. Alternatively, print information including a PIN code is returned to the image forming apparatus 20.

  The print information receiving unit 61 and the print information providing unit 63 are realized by a process in which one or more programs installed in the storage server 60 are executed by the CPU of the storage server 60. The print information storage unit 62 can be realized by using an auxiliary storage device of the storage server 60 or a storage device connected to the storage server 60 via a network.

  The image forming apparatus 20 includes an authentication control unit 221, a print information acquisition unit 222, a print control unit 223, and the like. Each of these units is realized by processing executed by the CPU 211 by one or more programs installed in the image forming apparatus 20. The authentication control unit 221 receives an input of a user name and password or a PIN code from the user. When the user name and password are input, the authentication control unit 221 requests the authentication server 50 to authenticate the user name and password. The print information acquisition unit 222 transmits a print information acquisition request to the storage server 60. In the acquisition request, at least one of the user name and the PIN code received by the authentication control unit 221 is designated. The print control unit 223 executes print processing on the print data acquired by the print information acquisition unit 222.

  Hereinafter, a processing procedure executed in the printing system 1 will be described. FIG. 5 is a sequence diagram for explaining a processing procedure of print data storage processing.

  In step S101, the user terminal 30 transmits a print request mail to the print request address in response to an instruction input from the user. Electronic data to be printed is attached to the print request mail. The print request address is, for example, a mail address determined in advance as a mail address addressed to the management server 10.

  However, when the user is a guest user, the guest user designates the mail address of any regular user in the Cc field of the print request mail. Hereinafter, the mail address specified in the Cc field is referred to as “Cc address”.

  As an example of the mail address designated as the Cc address, for example, the mail address of a regular user belonging to a department that is responsible for the cost of printing by the user can be cited. For example, a user needs to print a document for a meeting with a regular user a belonging to the department, and after obtaining approval from the regular user a, designate the mail address of the regular user a as the Cc address. It is possible.

  The mail server 40 transfers the print request mail to the management server 10 in accordance with a general communication protocol for transferring electronic mail (S102). If the Cc address is specified in the print request mail, the mail server 40 transfers the print request mail to the Cc address. As a result, a legitimate user whose mail address is designated as the Cc address of the print request mail can know the existence of a person who is trying to print using his mail address. Therefore, a regular user whose e-mail address has been used without permission can know it.

  The print request mail is received by the mail receiving unit 11 of the management server 10. Strictly speaking, the print request mail is acquired from the mail server 40 by the mail receiving unit 11. That is, a mail whose print request address is included in the To field, Cc field, or Bcc field is acquired from the mail server 40 by the mail receiving unit 11 as a print request mail.

  Subsequently, the address designation determination unit 12 determines whether or not the print request address is included in the correct format (specified) in the print request mail (S103). For example, it is determined whether or not the print request address is included in the To field or the Cc field in the print request mail. If the print request address is not included in either the To field or the Cc field, step S104 and subsequent steps are not executed. If the print request address is included in the To field or Cc field, step S104 and subsequent steps are executed.

  In step S <b> 104, the address confirmation unit 14 designates the transmission source address of the print request mail, and transmits the mail address existence confirmation request to the authentication server 50.

  In response to receiving the presence confirmation request, the request response unit 51 of the authentication server 50 confirms whether or not the mail address specified in the presence confirmation request is stored in the user information storage unit 52 (S105).

  FIG. 6 is a diagram illustrating a configuration example of the user information storage unit. In FIG. 6, the user information storage unit 52 stores user information for each authorized user. The user information includes, for example, a user name, a password, and an e-mail address. A plurality of e-mail addresses may be registered for one user, such as for PCs and mobile terminals.

  In step S <b> 105, the request response unit 51 confirms whether the mail address specified in the presence confirmation request is included as the mail address of any user information stored in the user information storage unit 52. .

  Subsequently, the request response unit 51 returns a response including the confirmation result to the management server 10 (S106). The confirmation result is information indicating whether or not the mail address exists. The address confirmation unit 14 receives the confirmation result.

  If the confirmation result indicates that the mail address does not exist and the Cc address is designated in the print request mail, the address confirmation unit 14 designates the Cc address and the existence of the mail address. A confirmation request is transmitted to the authentication server 50 (S107).

  In response to the reception of the presence confirmation request, the request response unit 51 of the authentication server 50 determines whether or not the email address specified in the presence confirmation request is stored in the user information storage unit 52 as in step S105. Confirm (S108). Subsequently, the request response unit 51 returns a response including the confirmation result to the management server 10 (S109). The confirmation result includes, for example, a user name corresponding to the Cc address.

  In response to receipt of the confirmation result in step S106 or S109, the management server 10 executes print information generation processing for the print request mail (S110). Subsequently, the mail reply unit 18 of the management server 10 returns a response mail to the print request mail to the transmission source address of the print request mail (S111). The response mail is transferred by the mail server 40 to the user terminal 30 that is the transmission source of the print request mail (S112). The response mail is generated in the print information generation process.

  On the other hand, after the response mail is returned, the print information transmission unit 19 of the management server 10 stores the print information including the print data generated in the print information generation process and the information associated with the print data. (S113).

  When receiving the print information, the print information receiving unit 61 of the storage server 60 stores (saves) the print information in the print information storage unit 62 (S114).

  FIG. 7 is a diagram illustrating a configuration example of the print information storage unit. In FIG. 7, the print information storage unit 62 stores print information for each print data. The print information includes a job name, a user mode, print data, a user name or a PIN code, and the like.

  The job name is identification information for each print data or each print job executed for each print data. The user mode is information indicating whether or not the transmission source address of the print request mail is managed in the user information storage unit 52. In the present embodiment, the user mode indicates whether the print request source user is a regular user or a guest user. “U” indicates a regular user, and “G” indicates a guest user. The user name is a user name of a user who is responsible for a print job based on the print information. The responsible user refers to, for example, a user who should bear the cost related to the print job (however, the actual loader may be a department to which the user belongs). The PIN code is a PIN code assigned to a user who is a print request source and is a guest user.

  Next, details of step S103 will be described. FIG. 8 is a flowchart for explaining an example of the processing procedure of the determination processing of the designation format of the print request address.

  In step S151, the address designation determination unit 12 determines whether or not the print request address is included in at least one of the To field and the Cc field in the print request mail. When the print request address is included in at least one of the To field and the Cc field (Yes in S151), the address designation determination unit 12 determines that the designation of the print request address is valid. In this case, step S104 and subsequent steps in FIG. 5 are executed.

  On the other hand, when the print request address is not included in either the To field or the Cc field, that is, when the print request address is included only in the Bcc field (Yes in S151), the illegal specification handling unit 13 An illegal designation handling process is executed (S152). In the fraudulent designation handling process, for example, a mail including a message indicating that printing is not permitted is transmitted to the transmission source address of the print request mail. The mail may include a message indicating that the print request mail should be specified in the To field or the Cc field.

  Alternatively, the unauthorized specification handling unit 13 may transfer the print request mail to all mail addresses included in the destination of the print request mail. In this case, the print request mail is also transferred to the authorized user designated by the Cc address. The print request mail is also transferred to the print request address. The To field of the transferred print request mail includes a print request address. Therefore, the transferred print request mail is determined to be valid by the address specification determination unit 12 regarding the specification of the print request address.

  The reason why the print request mail in which the print request address is specified only in the Bcc field is treated as invalid is to prevent the printing based on the print request mail from being performed without the knowledge of the authorized user. That is, if a print request address is specified in the Bcc field, a regular user's mail address is specified in the Cc field, and an appropriate mail address (for example, a guest user's mail address) is specified in the To field, When received by the authorized user, the authorized user cannot know that the mail is a print request mail. This is because the authorized user cannot know that the destination of the mail is the print request address. As a result, printing by the guest user is performed without the knowledge of the authorized user, which may cause an undesirable situation from the viewpoint of security. Therefore, in this embodiment, a print request mail in which a print request address is specified only in the Bcc field is treated as an illegal one, and printing based on the print request mail is suppressed.

  Next, details of step S110 will be described. FIG. 9 is a flowchart for explaining an example of the processing procedure of the print information generation processing.

  When the confirmation result received in step S106 in FIG. 5 indicates the presence of the transmission source address of the print request mail (Yes in S201), the address confirmation unit 14 sets the user name corresponding to the transmission source address. Obtained from the authentication server 50 (S202). That is, in the user information storage unit 52, the user name associated with the transmission source address is acquired.

  Subsequently, the print information generation unit 16 generates print data for each of the text of the print request mail and the attached electronic data (print target data) (S203). However, only the attached electronic data may be a generation target of print data. Further, when the electronic data is in an archive file format such as a zip format including a plurality of files, the print information generation unit 16 decompresses the electronic data and generates print data for each decompressed file. Accordingly, a plurality of print data (print jobs) can be generated for one print request mail.

  Subsequently, the print information generation unit 16 generates print information for each print data (S204). That is, a job name is generated for each print data and included in the print information. “U” is set in the user mode of each print information. Further, the user name acquired in step S202 is set in each print information. The print information generated here is transmitted to the storage server 60 in step S113 of FIG.

  Subsequently, the response mail generation unit 17 generates a response mail in which the job name of each print information is described in the text, for example (S205). The response mail is transferred to the user terminal 30 that is the transmission source of the print request mail in steps S111 and S112 in FIG. The user who browses the response mail can know the job name corresponding to each print data generated in response to the print request mail. However, when the transmission source address exists in the user information storage unit 52, the response mail does not necessarily have to be returned. For example, when the job name is generated based on the file name of the electronic data, the user can grasp the contents of the print data corresponding to each job name when operating the image forming apparatus 20 described later. Because.

  On the other hand, the confirmation result received in step S106 in FIG. 5 indicates the absence of the source address of the print request mail (No in S201), and the confirmation result received in step S109 indicates the presence of the Cc address. If it is shown (Yes in S206), steps S207 to S210 are executed.

  In step S207, the PIN code generation unit 15 generates a PIN code for each print request mail. The PIN code may be generated by any method as long as it has a different value for each print request mail. However, the PIN code is preferably composed of characters that can be easily input via the operation panel 25 of the image forming apparatus 20 or a software keyboard displayed on the operation panel 25.

  Subsequently, the print information generation unit 16 generates print data for each of the text of the print request mail and the attached electronic data (print target data) (S208). The processing content of step S208 may be the same as that of step S203.

  Subsequently, the print information generation unit 16 generates print information for each print data (S209). That is, a job name is generated for each print data and included in the print information. “G” is set in the user mode of each print information. Each print information is set with the user name included in the confirmation result in step S109 in FIG. 5, the PIN code generated in step S207, and the like. The print information generated here is transmitted to the storage server 60 in step S113 of FIG.

  Subsequently, the response mail generation unit 17 generates a response mail in which the PIN code is described in the text, for example, in addition to the job name of each print information (S210). The response mail is transferred to the user terminal 30 that is the transmission source of the print request mail in steps S111 and S112 in FIG. The user who has viewed the response mail can know the PIN code that is required to be input to the image forming apparatus 20 when printing the print data generated in response to the print request mail. Further, the user can know the job name corresponding to each print data. However, the job name does not necessarily have to be included in the response mail.

  When both the source address and the Cc address do not exist, or when the source address does not exist and the Cc address is not specified (No in S206), the response mail generation unit 17 generates, for example, an error message A response mail (hereinafter, referred to as “error mail”) including is generated (S211). In this case, an error mail is returned in step S111. In this case, print information is not generated. Therefore, steps S113 and S114 in FIG. 5 are not executed. That is, the user cannot perform printing.

  Thereafter, the user who has received the response mail other than the error mail goes to the installation place of the image forming apparatus 20 and operates the image forming apparatus 20. Next, a processing procedure executed by the image forming apparatus 20 according to a user operation will be described.

  FIG. 10 is a flowchart for explaining an example of a processing procedure executed by the image forming apparatus.

  For example, the authentication control unit 221 displays a login screen on the operation panel 25 in response to a call for a print function of print data stored in the storage server 60 (S301).

  FIG. 11 is a diagram illustrating a display example of a login screen. In FIG. 11, a login screen 510 has input areas such as a user name, a password, and a PIN code.

  For example, when the operator of the image forming apparatus 20 is a regular user, a user name and a password are input to the login screen 510. On the other hand, when the operator is a guest user, the PIN code notified by the response mail is input to the login screen 510.

  In addition, even if it is a regular user, a PIN code may be input. For example, when a regular user sends a print request mail from a mail address of the private user terminal 30, that is, a mail address not stored in the user information storage unit 52, a response mail returned to the user terminal 30 Includes a PIN code. On the other hand, the regular user may separately send a print request mail from the mail address stored in the user information storage unit 52. In this case, for the regular user, the print data associated with the PIN code and the print data associated with the user name are stored in the storage server 60. For both print data, both the user name and password and the PIN code may be input at the same time in order to enable execution of print processing with a single login operation.

  When at least one of the user name, password, and PIN code is input to the login screen 510 and the OK button 511 is pressed, the authentication control unit 221 determines whether the user name and password are input on the login screen 510. It is determined whether or not (S302). When the user name and password are input (Yes in S302), the authentication control unit 221 executes an authentication process (S303). Specifically, the authentication control unit 221 transmits an authentication request specifying the input user name and password to the authentication server 50. The request response unit 51 of the authentication server 50 determines whether or not the combination of the user name and password specified in the authentication request is stored in the user information storage unit 52. If the set is stored in the user information storage unit 52, the authentication is successful. If the group is not stored in the user information storage unit 52, the authentication fails. The request response unit 51 returns information indicating whether authentication is correct or not to the authentication control unit 221 of the image forming apparatus 20 that is the authentication request source.

  When the authentication is successful (Yes in S304), the print information acquisition unit 222 adds the user name input on the login screen 510 to the designation information (S305). The designation information refers to information that is designated when a list of print information is acquired from the storage server 60 in the subsequent step S308. If the authentication fails (No in S304), step S305 is not executed.

  If the user name and password are not entered in the login screen 510 (No in S302), if authentication based on the user name and password fails (No in S304), or following step S305, the print information acquisition unit 222 Then, it is determined whether or not a PIN code is input on the login screen 510 (S306). When the PIN code has been input (Yes in S306), the print information acquisition unit 222 adds the PIN code to the designation information (S307). If the PIN code has not been input (No in S306), step S307 is not executed.

  Subsequently, the print information acquisition unit 222 specifies the specification information and acquires a list of print information from the storage server 60 (S308). More specifically, the print information acquisition unit 222 specifies designation information and transmits a print information list acquisition request to the storage server 60. In response to the acquisition request, the print information providing unit 63 of the storage server 60 acquires print information including the designation information specified in the acquisition request from the print information storage unit 62 (FIG. 7). That is, when a user name and password are input on the login screen 510, the user mode is “U”, and print information including the user name is acquired. Here, the user name is also included in the print information based on the print request mail from the guest user in which the mail address of the regular user related to the user name is designated as the Cc address. Therefore, when a user name and password are input on the login screen 510, the user mode is “G”, and print information including the user name is also acquired. As a result, as will be apparent from the description below, the authorized user can cause the image forming apparatus 20 to execute a print job based on the print request mail from the guest user. By doing so, for example, when the image forming apparatus 20 is installed in an area where guest users are prohibited from entering, the authorized user can execute a print job on behalf of the user. However, in an environment where protection of confidential information included in the print request mail from the guest user is prioritized, the user mode is “G” when the user name and password are entered on the login screen 510. The print information including the user name may be excluded from acquisition targets.

  On the other hand, when a PIN code is input on the login screen 510, the user mode is “G”, and print information including the PIN is acquired.

  If both the user name and password and the PIN code are input on the login screen 510 and the authentication is successful, the user mode is “U”, the print information including the user name, and the user mode are “G” and print information including the PIN code is acquired. When both the user name and password and the PIN code are input on the login screen 510 and the authentication fails, the user mode is “G”, and print information including the PIN is acquired.

  The print information providing unit 63 returns a list of acquired print information to the image forming apparatus 20. Note that the print data returned here does not need to include print data.

  Subsequently, the print information acquisition unit 222 of the image forming apparatus 20 displays a list of job names and the like included in each returned print information on the operation panel 25 (S309). The list is a candidate for printing. That is, the user can input a print execution instruction for the print information included in the list.

  When one or more job names are selected from the list, the print information acquisition unit 222 acquires the print data corresponding to the job name from the storage server 60 (S310). More specifically, the print information acquisition unit 222 transmits a print data acquisition request in which the job name is specified to the storage server 60. In response to the acquisition request, the print information providing unit 63 of the storage server 60 returns print data corresponding to the job name specified in the acquisition request to the image forming apparatus 20. Hereinafter, the print information related to the selected job name is referred to as “target print information”.

  If only print information for one print data is acquired based on the input user name or PIN code, the print information acquisition unit 222 may acquire the print data without performing the process of S309. Further, the print information providing unit 63 may return the print data acquired based on the user name and the PIN code instead of returning the list of print information to the image forming apparatus 20.

  Subsequently, the print control unit 223 controls execution of a print job related to the print data (S311). As a result, a sheet on which the print data is printed is output. At this time, the log indicating the execution of the print job includes the user name included in the target print information. In the present embodiment, the user name is also included in the print information related to the user whose user mode is “G”. That is, the user name is included in any print information. Therefore, for example, when the expense billing destination for the execution of the print job is determined based on the user name, it is possible to determine the expense billing destination even for the print job by the user whose user mode is “G”. Note that the identification information of the billing destination and the correspondence information between each user name are stored in the HDD 214, for example.

  If the user mode of the target print information is “U”, that is, if the operator of the image forming apparatus 20 is a regular user, the print control unit 223 sets the user name input at the time of login in step S311. Execute the print job within the scope of the corresponding authority (print authority). On the other hand, when the user mode of the target print information is “G”, that is, when the operator of the image forming apparatus 20 is a guest user, the print control unit 223 displays the regular user associated with the guest user. Execute the print job within the authority. However, the print job may be executed within the range of authority for the guest user. The authority of each regular user may be stored in the user information storage unit 52, for example. The authority of each guest user may be stored in the guest information storage unit. The authority of each guest user may be common or may be different individually.

  As described above, according to the embodiment of the present invention, even a guest user whose account such as a user name and password is not registered in the authentication server 50 can be given print authority (output authority). Therefore, it is possible to reduce the necessity for the guest user to request printing from a regular user. In addition, the guest user is notified of a PIN code for each print request mail. Therefore, a pseudo and temporary account can be given for each guest user. Therefore, the print data that can be operated by each guest user is limited to the print data corresponding to the print request mail from the guest user. As a result, it is possible to avoid the occurrence of a situation in which print data of other users can be easily operated between guest users.

  Furthermore, the necessity of installing a dedicated image forming apparatus 20 for guest users can be reduced.

  In addition, in the Cc field of the print request mail from the guest user, the mail address of any regular user is designated. As a result, the regular user can be associated with the print job by the guest user, and the billing destination of the cost of the print job can be determined based on the association.

  In addition, even if the user is a regular user, a case where the regular user is treated as a guest user by transmitting a print request mail from a mail address different from the mail address registered for the regular user can be considered. Even in such a case, since the designation of the mail address of the authorized user is required in the Cc field of the print request mail, it is possible to determine the billing destination for the cost of the print job.

  Even if the mail address of the authorized user is specified in the Cc field, the print request mail in which the print request address is specified only in the Bcc field is treated as invalid. Therefore, it is possible to prevent a situation in which printing by the guest user is performed without the knowledge of the authorized user.

  Note that if the designation of the print request address is invalid, printing by the guest user only needs to be suppressed. Therefore, the determination process related to the designation of the print request address is performed at any timing before step S111 in FIG. It's fine. By doing so, the notification of the PIN code to the guest user who is the sender of the print request mail can be suppressed.

  Further, in the print request of the guest user, the designation destination of the regular user's mail address may not be the Cc field. The mail address of the regular user may be specified in the Bcc field, or may be specified in the To field together with the address of the print request mail. In other words, the mail address of the authorized user may be included in the transmission destination of the print request mail. In any case of the Cc field, the Bcc field, or the To field, the print request mail by the guest user is transmitted to the regular user, so that the regular user detects the registration of the print job in his own name. Can do. As a result, the authorized user can detect the registration of an unauthorized print job that is not intended by the authorized user.

  When the same guest user transmits a plurality of print request mails, a plurality of response mails each including a different PIN code are returned to the user terminal 30 of the guest user. In consideration of such a situation, a plurality of PIN codes may be input to the login screen 510. The print information acquisition unit 222 may acquire print information including any of the plurality of PIN codes from the storage server 60. By doing so, it is possible to eliminate the inconvenience of having to repeatedly log in and display a list of print information for each PIN code.

  Alternatively, the PIN code generation unit 15 of the management server 10 may store the generated PIN code in the auxiliary storage device 102, for example, in association with the transmission source address of the print request mail. When the source address of the print request mail is stored in the auxiliary storage device 102 in association with the PIN code, the PIN code generation unit 15 does not generate a new PIN code but stores the stored PIN code. Is output. In this case, a response mail including the PIN code is returned.

  In this way, when the same guest user transmits a plurality of print request mails, a single PIN code is assigned to the guest user instead of each print request mail. Therefore, the guest user can cause the image forming apparatus 20 to display and print a list of print information corresponding to a plurality of print request mails by inputting the PIN code on the login screen 510.

  It should be noted that the image forming apparatus 20 places restrictions on the printing of print data relating to print information acquired by specifying a PIN code, such as setting an upper limit on the number of prints or disabling color printing. Also good. By doing so, a large amount of printing or the like by the guest user can be prevented.

  The PIN code may be provided with an expiration date. A PIN code that has expired may be invalidated.
